Myopia, commonly called nearsightedness, is a refractive error of the eye that makes distant objects appear blurry while nearby objects remain in focus. This condition occurs when the eyeball is too long or the cornea (the clear front part of the eye) is too curved, which causes the incoming light to focus in front of the retina instead of on it. Myopia affects a significant portion of the population, with the prevalence varying among different ethnic groups and geographical regions. It usually develops during childhood or adolescence and may progressively worsen until early adulthood.
Myopia can have significant impacts on an individual's vision and overall eye health. Here are some of the common effects:
The risk for glaucoma is nearly 50% higher in individuals with moderate to high myopia compared to those with mild myopia.
Patients with severe myopia are at greater risk for retinal detachment and the associated complete vision loss than those with mild myopia.
Although not directly linked, myopia increases the likelihood of developing cataracts later in life and requiring cataract surgery.
The risk of macular degeneration associated with myopia (known as myopic macular degeneration) rises sharply with age and the progression of myopia.
Your optometrist plays an essential role in myopia control by providing early detection, monitoring, and treatment options for children, teens, and adults with myopia. Here are some ways optometrists can help in myopia control:
By working closely with patients and their families, optometrists can help prevent the progression of myopia and reduce the risk of associated eye problems, thereby promoting healthy vision and a better quality of life.
Put Digital Devices Away
There are so many screens in our kids' lives today (iPads, computers, cellphones) and a lot of these involve near work. It is unrealistic to ask kids to stop using these tools completely, but try to limit their usage throughout the day so there is more balance with outdoor time and activities that involve distance-vision (ie. looking at things more than 6m away).
Choose The Correct Viewing Distance
Avoid holding reading materials close to your eyes. Hold near-work activities further away to limit eye strain. Optimal “near range” (the distance that is most natural and comfortable for near work) can be measured with your own forearm. If you put your fist at your chin, the distance to the end of your elbow is an appropriate near position. Position your computer at a distance equal to the length of your arm from your shoulder to your wrist or finger tips.
Follow The 20-20-20 Rule
Give your eyes frequent breaks by following the 20-20-20 rule. Every 20 minutes, look at something 20 feet away, for 20 seconds. By following the 20-20-20 rule, you give your eyes a chance to relax and refocus on something in the distance. Prolonged near work (including screen time) is associated with an increased risk of myopia development. This practice can also help alleviate other symptoms associated with prolonged screen use, such as headaches and neck or shoulder pain.
Get Outside
Kids spend a lot of time indoors, especially during the winter months, so it is important ensure your kids spend at least 1-2 hours outside each day. This is important because they are more likely to be engaged in distance-vision activities when they are outside, which places less strenuous near-vision demands on growing, young eyes. It is also believed that dopamine release and Vitamin D from sunlight exposure also plays a role in slowing myopia progression. Spending time outside reduces the chance of developing myopia, but does not necessarily slow the progression once a child has already developed myopia, so outdoor time is important for even very young kids. Don’t forget your sunglasses!
There are several treatment options available for myopia, which include:
Your optometrist will recommend the most appropriate treatment option based on your age, lifestyle, and degree of myopia. It is essential to have regular comprehensive eye exams to monitor myopia progression and adjust treatment as necessary.

Myopia is becoming more common worldwide due to various factors such as increased urbanization, changes in lifestyle, and decreased exposure to natural light. Studies suggest that spending more time indoors and engaging in activities that require prolonged near work, such as reading and using digital devices, may contribute to the development and progression of myopia.
While it may not be possible to prevent myopia entirely, certain strategies can help reduce its progression, especially in children. These include spending time outdoors, taking regular breaks from near work (such as reading or using electronic devices), maintaining proper lighting conditions, and ensuring good posture during close-up tasks. Regular eye exams are also essential for early detection and intervention.
The rapid progression of myopia occurs in some people when certain factors are present. These include:
The most manageable factor that contributes to a rapid progression is insufficient control of nearsightedness through corrective measures. This can lead to continued elongation of the eyeball and faster deterioration of vision. Regular eye exams and proactive management strategies are crucial in addressing this issue.
